Apache Thrift
=============

Introduction
============

Thrift is a lightweight, language-independent software stack for
point-to-point RPC implementation.
Thrift provides clean abstractions and implementations for data transport,
data serialization, and application level processing. The code generation
system takes a simple definition language as input and generates code
across programming languages that uses the abstracted stack to build
interoperable RPC clients and servers.

Thrift makes it easy for programs written in different programming
languages to share data and call remote procedures.  With support
for [28 programming languages](LANGUAGES.md), chances are Thrift
supports the languages that you currently use.

Thrift is specifically designed to support non-atomic version changes
across client and server code.  This allows you to upgrade your
server while still being able to service older clients; or have newer
clients issue requests to older servers.  An excellent community-provided
write-up about thrift and compatibility when versioning an API can be
found in the [Thrift Missing Guide](https://diwakergupta.github.io/thrift-missing-guide/#_versioning_compatibility).

For more details on Thrift's design and implementation, see the Thrift
whitepaper included in this distribution, or at the README.md file
in your particular subdirectory of interest.

Thrift does not maintain a specific release calendar at this time.

We strive to release twice yearly.  Download the [current release](http://thrift.apache.org/download).
